Appliation filed July 14, 1921. Serial No. 484,576.

To all whom t may concern i Be it known that l SAMUEL H. NORTON -r s n a a citizen oit the United etates, residing at VlVleadvilleTin the eounty oit Crawford and State oiz Pennsylvania, have invented new and useful improvements in Slotting Tools, of which the iollowing is a specification.

This tool is designed to slot` rods in an ordinar,v automatic machine such as an automatie screw niaehine.

The inventien is illustrated in the aecompanying drawing which shows a ,central vertical section through the device,V the seetio-n being from the side et the ordinary machine.

1 marks the spindle nose of an automatic machine.7 a rofl held therebyg and k3 the ordinary sliding mounting for the usual holder i of' an automath:` machine. The sleeve 5 isflfed in the holder 4: and carries .a shaft- 6 whiehvis journaled in the sleeve 5. A head T is formed'on the end ot' the shaft 6,

Y the head forming a shoulder S abutting against 'the end oit the sleeve 5 and the shaft being held in place by a nut 9. Y

The head T is provided with a transverse hearing 10. cutter 11 is secured between the elmngiing washers 12. These washers are held liietween the spindles 13 and 14, the spindle 12% having an extension 15 extending hr-:wgh the washers 12 and cutter 11 so as to Center them. A holt 1G extends through a hevelled gear 1'? and through the sleeves 13 and le. The holt is provided with ahead 18 acting on the gear 17 at one end and with the nut 1S at the opposite end. It will readiliT he seen that as the nut 19 is set up all parts oi the spindle are clamped togetherl` the cutter being securely` clamped between the Clamping washers 12. The spindle sleeve 111 is provided with a head 14: and this in connection with the gear 17 locks the spindle against endwise movement in the hearing. The parts are so arranged as to size to prevent the clamping of the head 14a and the gear 17 against the faces of the head. The gear 17 is locked with the holt 16 hy means of a key 20.

AV gear 21 is fixed on the sleeve 5 hy means of a set serew 22 and as thesleeve 5 is fixed on the holder l the gear 21 is looked against rotation. Y

Clisteh pins 23 extend from the working face of the head 7 and engage the eluteh surfaces on J, eluteh ring 257 the clutch ring being lined on the work spindle or nose 1,.

in order to lubi'icate the hearing 10 I provide an axial opening 25 extending into the holt 16. 1i cap screw 26 provides a means by; which it may he opened for the introduction et oil. Radial openings 27 eX- tend through the sleeve spindles 13 and 14 from annular grooves 28. The annular Ygrooves register with radial openings 29 in the holt 1G leading from the axial opening 25.

The operation of the device is as follows: rThe work 2 is secured in the rotating nose and the head 7 is advanced in the usual manner h v moving the sliding mounting 3. As the pins engage the clutch surfaces 211 the head forced to rotate with the work sijlindle. The rotation oi the head 7 gives to the. hevelled Vgear 1'1" a planetary moveme s and as is in mesh with the `.L-ionary r 21 it is rotated von its axis givi to the spindle a rotative movement. lnasmuoh :is the head andworlr spindle are looked ether h v the detent elntel.a the rod` or and the Cutter held against rotation relaiivelgVVT to each other so that as the h ,al is af'lvanced the cutter forms a slot in the end of the rod.

lllhat l ela im as new is z* ln a slotting tool the combination of a cutter head having a transverse hearing therein; sleeve spindles arranged in the hearing; Clamping plates between the sleeve spindles; a cutter carried hy the clamping 'olatesg` a holt extending through the sleeve spindles and clamping the spindles and eut- 'ter together; a gear carried hy the holt; and a stationari7 gear meshing with the first mentioned gear.

In testimony whereof I have hereunto set in hand.
